Title: Ceramic tile feed to packing boxes - has computer holding tiles in buffer stores according to grade
Inventor: STEFANI FRANCO
IPC: B65B57/14
Filed: 1976-12-21
Abstract: The system assembles, separates and feeds to packing boxes ceramic tiles previously graded for quality by a computer. The speed of the conveyor for the tiles already graded is regulated so that the distance between adjacent tiles is sufficient to allow insertion of one or more. The separately selected tiles are removed under control of the computer and held in buffer store units until a number has accumulated in each sufficient to fill a box completely. The tiles from a store unit are then inserted in the intervals between incoming tiles of the same grade, and when processing of a batch of this grade is complete a changeover is made to another one. The computer halts the grading unit temporarily if one of the store units can take no more tiles in, and stops the complete conveyor if all are simultaneously full up.

Title: Radioactive components embedded in solidified slats mixt. in container - for storage or transport as compact easily remelted unit
Inventor: VOX ANTON J
IPC: G21F5/10
Filed: 1978-01-18
Abstract: A method of transporting and/or storing radioactive articles or substances consists of embedding them in a liquid salt of salts mixture in a transportation container, then allowing this mixture to set. When, after transportation and possibly a certain storage period, the articles or substances need to be removed again, the salt or salts mixture is remelted. Pref. the liquid mixture or salt is first placed in the container, then the articles or substances are placed in it. The mixture pref. has a relatively low melting point, esp. about 150 degrees C. Used for storing spent fuel rods and elements, radioactive machine components and handling equipment, contaminated garments, etc. The method enables compact handling and storage containers to be used and the salts mixture acts as a thermal buffer, since its latent heat of melting prevents the temperature from rising suddenly. In particular, temporary storage of used fuel elements without the use of a cooling pool or pond is possible. Thus considerable savings in space and equipment are achieved. Before the container is filled a pair of electrodes is immersed in it, projecting above the level of the solidified salt. To liquify the salts mixture layer, these electrodes are connected to electric potential and an already liquefied salt of salts mixture is poured onto the surface of the solidified salt or salts mixture to complete the electric circuit. Alternatively, heating rods are embedded in the salt. A transportable storage container filled as above is equipped with a cooler and heater and pref. also with temperature-conducting fins or walls.

The inlet hood adjoins the cylindrical jacket separating the final superheater straight tubes from the surrounding helical tubes, and itself contains a cylindrical baffle plate closely surrounding the lower part of the straight superheater tubes and containing a large number of radial bores. The inner cylindrical guide jacket for the helical tubes (outside the outer guide jacket for the straight tubes) continue downwards below the lower boundary of the helical tube bundle and is fixed to a support grating. the grating in turn is secured to an outer support skirt continuing downwards to the inlet opening for the coolant inlet duct. At its bottom, the support skirt continues into a series of vertical columns resting upon the base of the pressure vessel vault. The feed water lines and live steam lines pass downwards from the generator, the live steam lines being located coaxially around the centre of the steam generator. A concentric inlet flow of the reactor coolant gas into the final stage of the superheater is achieved. The assembly can be mounted to stand on the floor of the pressure vessel vault. Access for maintenance and inspection is facilitated.
